#Solar #energy is the
️ most widely available energy resource on Earth,
and its economic attractiveness is improving fast in a cycle of #increasing #investments.
Here we use data-driven conditional technology and economic forecasting modelling to establish which zero carbon power sources could become dominant worldwide.
We find that, due to technological trajectories set in motion by past policy,
a global #irreversible solar #tipping #point may have passed where solar energy gradually comes to #dominate global #electricity #markets,
without any further climate policies.
Uncertainties arise, however, over #grid #stability in a renewables-dominated power system,
the availability of #sufficient #finance in underdeveloped economies,
the capacity of #supply #chains and #political #resistance from regions that lose employment.
Policies resolving these barriers may be more effective than price instruments to accelerate the transition to clean energy
